The atomic weight of an element is determined by what?

The atomic weight of an element is determined by the weighted average of the masses of its isotopes, taking into account their abundance in nature. This value is typically found on the periodic table as the average atomic mass of the element.


How do you get the atomic number and weight?

The atomic number of an element is equal to the number of protons in its nucleus. The atomic weight is the average mass of an element's isotopes, taking into account their relative abundance. Both the atomic number and weight can be found on the periodic table for each element.


What does the atomic mass of an element tell?

The gram atomic weight or gram Atomic Mass of a chemical element is the mass in grams of Avogadro's number of atoms of the element with the isotopic proportions found in nature.


Average weight of an element expressed in atomic mass units?

The average weight of an element is expressed in atomic mass units (amu) and is calculated based on the relative atomic masses of the isotopes of that element weighted by their abundance in nature. This value can be found on the periodic table for each element. For example, the average atomic mass of carbon is 12.011 amu.


What element has 121.75 as it's atomic weight?

The element of Antimony (Sb) would have the atomic weight of 121.75.


What is the element to this atomic weight 32?

Sulfur (32.065)


What are the main contributors to the weight of an atomic element?

The protons and neutrons are the main contributors to the weight of an atomic element.


Which element has an atomic weight?

All elements have an (atomic) weight or mass.


How can one determine the atomic weight of an element?

The atomic weight of an element can be determined by calculating the weighted average of the masses of its isotopes, taking into account their abundance in nature. This information is typically found on the periodic table of elements.


What element has an atomic mass of 50.942?

Vanadium is the element that has an atomic weight of 50.942.


What is the atomic mass is an element?

The atomic mass of an element is the weight of the constituent atomic paraticles in an atom of a given isotope. The atomic weight is the weighted average mass for atoms in a naturally occurring sample of the element.Almost all of an atom's mass is found in the nucleus, consisting of protons and neutrons.
